“…This positive effect could be explained upon the effect of SA on increasing CO2 assimilation and accordingly photosynthetic rate in addition to the increase in mineral uptake (Karlidage et al 2009). Another explanation for the positive effect of SA on growth and yield could be its influence on other plant hormones which play a fundamental role in the auxin, cytokinin and ABA balances (Shakirova, 2007).…”

Foliar application effects of salicylic acid (SA) and gibberellic acid (GA 3) were investigated on growth and flowering of Ixora coccinea L. plants. Four concentrations (100, 200, 300 and 400 ppm) of both SA and GA 3 were sprayed in addition to the control (water-sprayed plants). Results indicated that all growth and flowering characteristics of Ixora plants were increased by all concentrations of SA or GA 3 compared to the untreated plants. Concerning salicylic acid, the lowest concentration (100 ppm) produced the highest plants while 200 ppm increased leaf area and shoot/root ratio. Number of leaves and plant pigments (chlorophyll a, b, a+b and carotenoids) were increased at 300ppm concentration. Spraying the plants with 400ppm increased fresh and dry weight of shoots and roots and flower number. GA 3 sprayers at 300 or 400ppm led to a significant increase in most of the characteristics studied in comparison to the untreated plants. The correlation coefficient among most of Ixora vegetative and flowering growth characteristics proved to be significant.

“…However, it also affects ethylene biosynthesis and enhancement of plant photosynthetic pigments such as chlorophyll and carotenoids (Hayat et al, 2007). Nine blackcurrant transcripts had homology to Arabidopsis SA associated proteins, including immune signal receptor NPR3 (at5g45110) (Fu et al, 2012), three TGA transcription factors (TGA2, TGA4, and TGA9) and PR1 induced in response to a variety of pathogens.…”

A Transcript and Metabolite Atlas of Blackcurrant Fruit Development Highlights Hormonal Regulation and Reveals the Role of Key Transcription Factors

Blackcurrant fruit collected at six stages of development were assessed for changes in gene expression using custom whole transcriptome microarrays and for variation in metabolite content using a combination of liquid chromatography-mass spectrometry and gas chromatography-mass spectrometry. Principal components analysis demonstrated that fruit development could be clearly defined according to their transcript or metabolite profiles. During early developmental stages, metabolite profiles were dominated by amino acids and tannins, whilst transcript profiles were enriched in functions associated with cell division, anatomical structure morphogenesis and cell wall metabolism. During mid fruit development, fatty acids accumulated and transcript profiles were consistent with seed and embryo development. At the later stages, sugars and anthocyanins accumulated consistent with transcript profiles that were associated with secondary metabolism. Transcript data also indicated active signaling during later stages of fruit development. A targeted analysis of signaling networks revealed a dynamic activation and repression of almost 60 different transcripts encoding transcription factors across the course of fruit development, many of which have been demonstrated as pivotal to controlling such processes in other species. Transcripts associated with cytokinin and gibberellin were highly abundant at early fruit development, whilst those associated with ABA and ethylene tended to be more abundant at later stages. The data presented here provides an insight into fruit development in blackcurrant and provides a foundation for further work in the elucidation of the genetic basis of fruit quality.

“…Both compounds were recorded in the KEGG Pathway of map01060 (biosynthesis of plant secondary metabolites) and map01065 (biosynthesis of alkaloids derived from histidine and purine). Salicylate, on the other hand, is an important phenolic phytohormone mediating in plant defense against pathogens [28].…”

In this study, a high-performance liquid chromatograph and an electrospray ionization (ESI) triple quadrupole mass spectrometry (TQ MS) detector were used to scan Oriental Beauty tea of different grades and prices. Principle component analysis (PCA) of the profiling data was performed for pattern recognition, clearly showing that the proposed MS profiling method was able to classify Oriental Beauty tea into different grades. The component mass ions primarily responsible for the separation were selected with high loading strength in the PCA for subsequent identification with tandem mass (MS/MS). Caffeine, citrate and salicylate were verified, whereas certain other compounds remained ambiguous. Regression analysis considering caffeine, citrate and salicylate showed a linear relationship between the prices of the Oriental Beauty tea with an adjusted R2 of 0.84. If all the selected marker ions (in addition to caffeine, citrate and salicylate) could have been identified and incorporated into regression analysis, a stronger relationship could have been confirmed. These results suggest that metabolomics can facilitate the determination of real markers in the quality control of Oriental Beauty tea, and may lead to the further application of metabolomics in other food quality controls.
